SPECIFICATION forming part of Letters Patent No. 391,813, dated October 30, 1888.

Application filed August 24,1888. Serial No.283,665. (Nomodel.) i

To @ZZ whom, it may concern.-

Be it known that I, RALPH H. NORTH, a citizen of the United States, residing in the city and county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Sash-Holders, ofwhich the following is a specification.

The present invention relates to that class of sash holders or locks in which a movable member is held in an open socket. It, however, relates more particularly to the class of sash holders or locks set forth and shown in United States Letters Patent No. 37 9, 242, granted to me March 18, 1888.

The invention consists in providing a sashholder that is composed of separable members with a detachable confining-plate, whereby when the members are assembled and not connected with a sash the plate will hold them together and prevent them from becoming disassociated, the construction being such that the plate is detachably secured in place and prevented from accidental dislodgment.

The accompanying drawings illustrate the improvement in connection with a sash-holder substantially like that shown in my said patent, in which drawingsm Figure 1 is a perspective view looking at the under side of a case containing a movable bolt or catch and provided with the improved coniningplate. E ig. 2 is a sectional elevation of the same, taken on the line 2 2 of Fig. l, shownin position and secured to a sash. Fig. 3 is a plan view of the under side of the case, the movable bolt or catch and confining-plate being removed. Fig. a is a perspective view of the confining-plate.

Prior to my invention it had been found dei sirable to form the case for the movable bolt with an open socket for containing the bolt, so as to obviate the necessity for using a core in the casting operation to form an inclosed socket therefor, and in order to prevent the movable bolt from wearing away the sash it became necessary to supplement the case with a plate adapted to be contained in a recess in the under side of the case and below the bolt, which plate was a loose one and only held to its place when the case was secured to the sash. ln such a construction it is obvious that said loose plate had no effect to hold the parts of the lock together when not secured to the sash,

and when the case was handled it necessitated also handling the plate, and when it was to be secured to the sash it required that the plate be carefully inserted in place in its recess in the case and kept so until the case was properly secured.

ln order to obviate these disadvantages and to increase the efficiency of this class of devices, the improvement consists, essentially, in providing the under side of the case with a seat for a detachable plate and a plate adapted to said seat and held therein against accidental displacement, whereby when the parts were assembled they would remain so until it was desired to disassociate them by removing the plate.

The sash-lock taken for illustration consists, as in my said patent, of the bolt section or case A, having an open socket, d, from which socket extends horizontal flanges e, providing` means for securing the section or case to the rail of a sash, B. TWithin the socket d is seated the cylindrical bolt C, having a locking-finger at its outer end and provided with an operatinghandle, b, which extends through a cam-slot, c, in said socket of the section or case. With this section of course will be used a keeper adapted for attachment to the meetingmail of the other sash, and with which keeper the end of the bolt C engages as it is turned for that purpose, and by which the two sashes are se cured. As this portion of the sash holder or lock forms no part of the present invention,no illustration of the same is given. keeper is fully shown and set forth in my said patent.

The under side of the case A,and upon opposite sides of the depression formed by the socket d, is formed with a depressed seat,l0extending substantially the width of the case, as shown, and providing shoulders l2 upon the opposite sides of the seat to better confine the plate D in place. These shoulders may be undercut to provide overlapping tongues to engage with the plate and hold it in place in the seat. In

practice, however, I prefer to provide one or more tongues, 13, upon opposite sides of .the depressed seat l0, the inner edge of which ex- IOO tends slightly beyond the line of lthe shoulder 12 upon the sameside of the seat,which tongues are undereut,as shown at 9, Fig. 2,so as to permit the edges of the plateD when moved into proper position in the seat to extend between said tongues and the seat, thus holding the plate in place. The opposite edges of the plate D may be inclined, as shown, to better adapt it to slide between the tongues and the seat and be properly held by said tongues. The tongues 13 may also extend slightly beyoud the surface or under side of the oase A, as shown in Fig. 2, and thus strengthen them considerably. While these tongues may be placed at any point along the sides of the depressed seat, they are preferably located at the points at which the cam-slot c, formed in the socket d, meets the horizontal flanges e of the ease, and, as shown, extend from said flanges inwardly over the opening formeel by said camslot. This greatly simplilies the construction of the case and tongues and renders their man ufacture as easy as in cases without the tongues, theposition of the tongues and their uncutsides being suited to the draft in the casting operation.

The plateD may be more effectively held in place by the tongues 18 by forming it slightly tapering in width, so that when it is slid onto its seat from the open end thereofthe plate may be pushed hard enough under the tongues to i become wedged sufficiently therebetween to withstand ordinary handling and prevented from becoming loose. The seat l0 ol' course may also be slightly tapered to correspond with the taper ot the plate D.

l. The herein-described ease for sash-holders, provided upon its under side with a seat having oppositely-projecting tongues andadetachable plate adapted to said seat and to be removably held in place by said tongues.

2. The herein-described case for sash-holders, provided upon its under side with a seat having oppositelyprojecting and undercut tongues and a detachable plate having inclined or beveled sides adapted to said seat and to be removably held in place by said tongues.

3. The herein-described ease for sash-holders, provided upon its under side with a seat having oppositely-proj ecting tongues and a detachable plate tapering in width, adapted to slide on the seat under the tongues and be wedged between the tongues and the seat.

4. The herein-described case for sash-holdp ers, having an open socket, a revolving bolt contained thereby, and a eam-slot for projecting the bolt, the said case provided with 0ppositely-projeeting tongues extending over the opening formed by the cam slot and a removable plate adapted to be confined to the ease by said tongues.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
